Product Description

Product Overview

The CH910/CH910L are Hall effect sensors designed for detecting magnetic poles. They feature a low supply current in both awake and sleep modes, making them suitable for power-sensitive applications. The sensors offer a fast awake time and a configurable period, with a high chopping frequency for efficient operation. They are available in SOT-23-3L and TO-92S packages.
